Anti-ganglioside antibodies reveal subsets of cultured rat dorsal root ganglion neurons.
Subsets of cultured dorsal root ganglion neurons were identified by using the anti-ganglioside monoclonal antibodies A2B5, D1.1, R24 and JONES. A2B5 and D1.1 labelled a population of cells that was relatively stable between 2 and 20 days in vitro, while the population of cells labeled with both R24 and JONES decreased with time, suggesting that the gangliosides recognized by Jones and R24 are developmentally regulated. Given the observation that the relative proportions of ganglioside species changes with time in culture, it is very important to carefully define the stability of ganglioside antigens before using them as cell markers.
